public class RequestHandler
extends AjpHandler

Handle messages related with basic request information. This object can handle the following incoming messages: - "FORWARD_REQUEST" input message ( sent when a request is passed from the web server ) - "PING REQUEST" input message (sent by the web server to determine if tomcat is not frozen, a PONG REPLY will be sent back) - "RECEIVE_BODY_CHUNK" input ( sent by container to pass more body, in response to GET_BODY_CHUNK ) It can handle the following outgoing messages: - SEND_HEADERS. Pass the status code and headers. - SEND_BODY_CHUNK. Send a chunk of body - GET_BODY_CHUNK. Request a chunk of body data - END_RESPONSE. Notify the end of a request processing.
